You are adding air to a tire. The air pressure in the tire should be 24 27 200 pounds per square inch. What decimal should you w
vova2212 [387]

Answer:

P = 24.135 pounds per square inch

Step-by-step explanation:

The air pressure in the tire should be 24\dfrac{27}{200} pounds per square inch. This pressure is in the form of a mixed fraction. It is required to convert this pressure into a decimal form. We can convert it as follows :

24\dfrac{27}{200}=\dfrac{(24\times 200)+27}{200}\\\\=24.135\ \text{pounds/square inch}

In decimal form, the value of pressure in the tire on the digital pressure gauge is 24.135 pounds per square inch.

Calculate 8% of 300 (0.08*300) and add 300 (+300)

0.08(300)+300\\24+300\\324

For the function f(t)+Pe^rt, if P = 8 and r = 0.08, then what is the value of f(8) to the nearest tenth?
Bogdan [553]
F(t) = P.e^(r.t) [ and not as you wrote it  f(t)+Pe^rt]
plug in:

f(t) = 8.e^(0.08t) (where e = 2.718 and t=8 given, f(8))
f(8) = 8.(2.718)^(0.08*8) = 21.74^(0.64)

f(8) = 7.17
